This is another reason I point out we have THREE tags on the dogs AND the chip which is kept updated.
Right there on the collar -- Tag 1 traditional contact info. Tag 2 -- county tag registered to ME. Tag 3 -- microchip contact phone number and chip number.
Of course, I uses Dog Tag Art with the swivel mount so whichever side it swings I get a cute picture with the county tag in between. I have a KeepSafe breakaway collar for crating times and times we are gone and a nice fancy collar to swap to when we have a nice outing.
What if a dog bolts out a door or walks out an unlatched gate or a window breaks or there is a car accident? Or like my Quay, we almost got hit by a radio controlled jet! The more ID the better.
My questions on the Piper story are why didn't the dogsitter run RIGHT to the shelter and call the owner immediately? Why didn't the owner show up with papers, pix, a letter from the vet (or even the vet him/herself?), and a sheriff? I would have. Why didn't the vet take take the time to look up that chip? I mean, "Hi vet, we have this bi black female sheltie that you chipped and we need the contact info". "Gosh, that sounds like Piper, pull the file, call Ms. Owner right now! Someone go get the uber valuable animal right this moment and bring her here to our vet's office for the weekend and we will give her back to Ms. Owner. We will board her." Think about it. What's up with "oh, we will look it up on Monday, call us back in 3 days". Why wouldn't the vet know the dog? How many bi black show quality female shelties does that practice have? My vet knows my three dogs by name! I would (figuratively speaking) kill the vet if my dog were in a shelter and they did NOTHING. My dad always said two wrongs don't make a right. While the owner didn't do anything wrong, she did it average, like you would for any animal lost, it was all just casual. If my show girl was lost I would have moved heaven and earth immediately before this could build into a horrifying and baffling story.
